# Sell

The Simple E-Learning Language (=: SELL) is an open standard for mathematical e-learning questions with the following objectives:

• Simple syntax: No unneeded overhead. Defining a task/question should be similar to describe the task/question on a blackboard.
• Expressive langage: Programs are short and concise such that the semantics can be grasp quickly. Irrelevant detail is avoided.
• Reuse of established standards: It inherit AsciiMath for mathematical expressions and Markdown for text formatting.

Project maintainer: Andreas Schwenk / TH Köln.
